Just had the game crash to Main Menu. The message panel said that it was due to a mod conflict and suggested disabling all mods. the thing of it is though, the only mods that were active were the Firaxis DLCs and expansions. So is this a GS bug or what? ADDENDA: Tried to Resume from that Main Menu screen. Crash. Managed Mods and disabled all of the official mods except for the R&S and GS expansions. Resume = crash. Exited the game entirely and restarted it. Resume = crash. Started fresh again, but instead of Resume, Loaded a Save from a short while before the first crash hit. Crash. It looks like the game has become unplayable. My next step will be to start a fresh game and see if the crashes start again along about the same Turn number.
